Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less. Because of their fairly simple design, ball mills and pebble mills are less likely to need costly repairs (unlike other crushing or extraction equipment) making them an attractive option for businesses on a budget.
The ball mill liner is used to protect the cylinder body from direct impact and friction of the grinding body and the material. At the same time, different forms of mill liner can be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material, Help to improve the grinding efficiency.
